Surface Preparation

Anyone familiar with SSPC AB-2 Specification and soluble salt testing?  We have several AISC Certification Fabrication shops across the US and none of us have been performing this unless contract documents require it.  I just realized cleanliness standards SP-7/6/5/10 all state follow AB specs for this.  

Looking for a way to reduce this since it seems a bit excessive performing soluble salt testing 12 hrs / every shift.

I have contacted several other fabricators and other coating manufacturers as well as blast media manufacturers and no body has even heard of the AB Specs nor have they known soluble salts of blast media and the blast cleaned materials to be a problem.  Even checked with mills that ship from states using salt on roads or coastal areas.

If there isn't a way to reduce the frequency, what is the process of getting AMPP to give an official interpretation and / or changing the AB spec?

Noah,

I'm not a lot a help on the fab shop side of the conversation, but I've seen the test run quite a bit in the field when using mobile recyclers. The ASTM D4940 conductivity test required by AB-2 utilizes a reusable device  and really does not take long to run.  Once implemented into the work flow it likely won't feel excessive. 

With that, I would strongly suggest NOT changing the standard. The point of the test frequency is to ensure that recycling systems are still functioning as intended. Stuff breaks and limiting the amount of production that occurs between the malfunction and becoming aware of the malfunction is worth the effort of running a short test every 12 hours of production.
